4 Conjugation in E. coli
... E. coli’s chromosome is one continuous DNA-molecule, about 1.3 mm on length. In the cytoplasm of some E. coli-strains, is a so-called F-factor which is a small circular DNA molecule which goes under replication independent to the chromosome’s replication. The Bacteria which have the F-factor are cal ...
